Base Station – CPE quickstart
The most common wireless network architecture is Point-to-Multipoint (P2MP), in which a central unit, the Base Station (BS), coordinates all the other units connected to it. These units are called CPEs and are supposed to be connected to the internet through the BS.
An equivalent name for the Base Station is Access Point. CPEs are commonly referred also as Stations or Clients
Base Station quick configuration
It is strongly suggested to stage the units before installing them on the site.
Always check that the firmware on the device is up-to-date. It is highly recommended to upgrade the device with the latest firmware (Check here).
All Bitlomat devices operate by default as Base Stations. However, the quick configuration procedure can be accessed from the Change Mode action in the Main menu.
The second step consists in configuring the WAN settings. In BS mode, the WAN indicates the configuration of the Ethernet of the unit that connects to the Internet. A common way to configure the WAN settings is to choose Static as IP assignment method and then input a static IP address/netmask unless you want the address to be assigned to the BS dynamically through DHCP. It is likely that there will be a gateway between the BS and the Internet, so the Gateway field is usually necessary.
The final step consists in filling the Wireless settings. Wi-Fi settings are:
- Country Code:
choose the nation in which you are using the device. Each nation has a different list of allowed frequencies. Choosing a wrong country code may cause an illegal operation of the device.
- Channel width:
it represents the spectral width of the wireless channel. Choose “40” for maximum throughput.
- Frequency/Extension Channel:
choose one of the channels in the list.
choose one SSID for the wireless network.
choose the security method for the wireless network.
It is recommended to enable security and to override the default SSID.
Save and Apply.
CPE quick configuration
In the first step, the Wireless settings must be filled. Change the Wi-Fi settings in accordance with the BS ones. If the BS is still on, the SCAN button can be used to detect it and automatically fill the Wi-Fi settings.
In CPE mode, the Channel width option has a unique entry for 20 and 40 MHz. When the 20/40 option is selected the CPE will automatically configure the right channel width accordingly with the BS configuration.
Finally, configure the LAN settings. In CPE mode, they refer to the Ethernet side of the unit. The easiest way to configure LAN settings would be to choose Bridge as Network Role. However, we discourage to configure CPEs as Bridges. It is always a good practice to keep the ISP network and the user network strictly separated. For this reason, we suggest to select Router as Network Role and then choose a custom IP address for the network interface.
Enabling the DHCP Server the unit will assign a free IP address in the specified range whenever a device would connect to the LAN network.
Save and Apply.
All other CPEs can be configured in the same way, just choose a different WAN IP address.
In order to verify that everything is ok, power up all the configured units. Connect a PC (PC-1) directly to the BS Ethernet port and open the web GUI. All CPEs must be present in the DASHBOARD Wireless Analytics. Furthermore, all CPEs must be accessible using their WAN IP address (e.g. 10.10.0.100).
Note that, when a Bitlomat unit is configured as a Router for the first time, the NAT Service is automatically activated. In fact, connecting another PC (PC-2) directly to a CPE Ethernet port, it should be able to ping PC-1. The following is a possible scheme of the final network. The private LAN behind each CPE represents a different broadcast domain so that broadcast traffic from one LAN doesn’t affect other private LANs and the backbone network. On the other hand, from the backbone network, all the units can be accessed at their WAN IP addresses.
- WAN IP assignment method:for units configured as Router the PPPoE option is available.
